For those who are concerned with loudness my suggestion would to go w/ either Cherry browns or red switches. Then grab some key dampeners, which are just o-rings that go on the bottom of the key cap. It prevents the cap from bottoming out. I installed them on my cherry blues and it sounds fantastic. You can buy them pre-installed on WASD Keyboards.

That's a fantastic idea...never knew those dampeners existed. I have a DAS keyboard at work with mx browns and a Leopold keyboard at home with cherry blues that I going to have to try them on
